“The Leaping Leopard” - Simeis 3-210

This wonderful wispy area of nebula is a supernova remnant in the extreme southern part of the Veil in the constellation of Cygnus called Simeis 3-210. I photographed this quite a few years ago and just got to reprocessing it.

With its long, thin filaments of Oxygen 3 and Hydrogen It’s virtually an unknown and not often imaged part of this large supernova remnant, at least at this long focal length.

Ten thousand years ago, before the dawn of recorded human history, a new light would suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was from a supernova, or exploding star, and record the expanding debris cloud as the Veil Nebula, a supernova remnant. Imaged with narrow band filters, the glowing filaments are like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas.
